Definitions

  • the present invention relates to a composition for producing a layer or a coating, in particular a shaped release layer, a method for producing such a composition, the layer or coating produced and articles coated with the layer or coating.
  • a release agent to the surfaces of tools, auxiliaries and in particular of molds which come into direct contact with the liquid materials.
  • a release agent which is commonly referred to as a mold release layer
  • the adhesion of the melt to these surfaces should be as low as possible both in the liquid and in the solid (cooled) state.
  • a casting can be more easily released from a mold, which is provided with a mold release layer.
  • a mold release layer reduces the wear of a mold and has a correspondingly positive effect on its durability.
  • Mold release liners should not adhere to the surfaces of castings and, if applied as a wear finish, should not bond too tightly with the surfaces of the molds, tools or aids.
  • a mold release layer should be non-flammable and also environmentally friendly, which means in particular that outgas no toxic substances at high temperatures should.
  • mold release layers are produced in as even layer thicknesses as possible by brushing or spraying on a spreadable or sprayable composition. Such a composition for the production of mold release layers is also referred to as sizing.
  • Inorganic mold release layers are therefore generally preferred in the processing of hot metal or glass melt.
  • mold release layers are usually based on the compounds graphite (C), molybdenum disulfide (MoS 2 ) and boron nitride (BN), the latter in particular in its hexagonal form. Mold release layers based on these materials are characterized by their extremely low wettability by molten metals. They have particularly low wettability compared to aluminum and magnesium melts and to melts of aluminum-magnesium alloys. While graphite in the air is already oxidized at temperatures of around 500 ° C. and molybdenum disulfide even as low as 400 ° C., boron nitride is stable under the same conditions up to about 900 ° C.
  • boron nitride is particularly suitable as a constituent of mold release layers for high temperature use.
  • both mold release layers based on graphite or molybdenum disulfide and those based on boron nitride are generally not very abrasion resistant.
  • the processing of light metal melts or glass melts (melts in which high flow rates occur) has high mechanical requirements, which the known inorganic mold release layers are permanently not meet.
  • the mold release layers known from the prior art wear wear correspondingly very quickly, are therefore usually not intended for repeated use and must be renewed regularly.
  • the object of the present invention is to provide a mold release layer which does not have disadvantages known from the prior art.
  • a mold release layer according to the invention should be as inert as possible as well as oxidation resistant to metal melts.
  • a mold release layer of the invention should have a low wettability to metal and glass melts and at the same time be resistant to abrasion. It should be able to withstand high mechanical loads, which occur, for example, in the processing of melts with high flow velocities, and thus be suitable for multiple use (even with permanent loading over several days and weeks).
  • compositions having the features of claim 1 and the use of the features of claim 25 Preferred embodiments of the composition according to the invention are described in the dependent claims 2 to 19.
  • a layer or coating which can be produced from a composition according to the invention is defined in claims 20-23, an article at least partially coated with such a layer in claim 24.
  • a method for producing a composition according to the invention is subject matter of claims 26 and 27. The wording of all claims is hereby incorporated by reference into the content of this specification.
  • a composition according to the invention for producing a layer or a coating, in particular a mold release layer contains either aluminum titanate, silicon nitride or a mixture of both as component A.
  • Aluminum aluminumate-containing compositions are particularly preferred according to the invention.
  • a composition according to the invention has an oxidic inorganic component B (aluminum titanate, which is strictly speaking also an oxide, should be excluded as a possible component of component B) and a binder with nanoscale particles as component C and in a preferred Embodiment a suspending agent as component D.
  • the particles of component A have an average particle size> 500 nm, in particular> 1 ⁇ m.
  • average particle sizes between 100 nm and 1 ⁇ m, in particular between 200 nm and 1 ⁇ m, are particularly preferred. If appropriate, oxide particles with average sizes in the microenvironment, in particular up to a size of 10 .mu.m, may also be preferred.
  • the nanoscale particles of the binder component C are preferably substantially smaller, namely they have in particular average particle sizes of ⁇ 50 nm, in particular ⁇ 25 nm.
  • the mode of operation of a binder with such nanoscale particles is described in detail in WO 03/093195.
  • the binder used in the binder nanoparticles have very large specific surfaces, which are preferably coated with reactive hydroxyl groups. These surface groups are capable of crosslinking at room temperature with the surface groups of the (usually coarser) particles to be bound. At temperatures above 200 ° C., preferably above 300 ° C., due to the extremely high surface energies of the nanoparticles, material transport sets in towards the contact points of the particles to be bound, which leads to further solidification.
  • an average particle size between 1 ⁇ m and 25 ⁇ m, preferably between 1 ⁇ m and 10 ⁇ m, in particular between 2 ⁇ m and 10 ⁇ m, is more preferred. In a particularly preferred embodiment, the average particle size for the particles of component A is about 5 microns.
  • the particles having the size distribution as defined above can be arranged particularly advantageously in the resulting layer or coating.
  • smaller particles are stored in interstices that remain free between adjacent coarser particles, resulting in a structure of increased density, the cohesion of which is again ensured by the nanoscale binder (component C), which fixes and reinforces the contact points between the particles.
  • the inorganic oxide particles of component B are preferably ceramic particles having a Mohs hardness> 6. Particularly suitable are binary oxidic compounds, in particular particles of aluminum oxide or titanium dioxide, but mixtures of both may also be preferred.
  • the most important criterion in selecting the particles of the binder component C is their size, which should not exceed on average 50 nm as indicated above.
  • the particles are, in particular, oxidic particles, preferably aluminum oxide, zirconium oxide and / or titanium dioxide particles or precursors of these compounds. With regard to favorable wetting properties (especially with respect to light metal melts), in particular mixtures of titanium dioxide particles with aluminum oxide particles or boehmite particles have proven particularly suitable.
  • the binder in addition to the nanoparticles mentioned at least one organosilicon component from the group
  • the at least one organosilicon constituent may be, for example, in

  • Mica in particular micronized mica, is also eminently suitable.
  • a layer produced from such a composition protects, for example, tools, aids and molds not only from adhesions, but also with particular advantage from the high thermal stresses that can occur, in particular, in contact with liquid metal melts.
  • the suspending agent optionally contained in the composition is preferably polar. It is particularly preferred that it has water as the main constituent, but in principle it may also contain other polar components such as, for example, alcohols.
  • the composition of the invention comprises a suspending agent which is free of nonaqueous liquid components.
  • a composition according to the invention contains at least one surface-active substance, in particular a polyacrylate.
  • a surfactant has proved particularly advantageous in cases where the suspending agent is free of nonaqueous liquid components.
  • compositions according to the invention may comprise boron nitride as an additional component. It has been found that a proportion of boron nitride has a positive effect on the flexibility, in particular the susceptibility to cracking and the elasticity, of the layer or coating to be produced. This applies in particular to layers / coatings based on compositions containing aluminum titanate or silicon nitride as component A and aluminum oxide as component B.
